Hydrogen can work. This is America (plus Toyota). Why say we can't do something. In the meantime, hybrids and ethanol and the rest. Plus drive less. Solar and wind. Get your panels. During WWII we rationed gas. Why not ask the people to sacrifice some of their wasteful driving habits?

"Hydrogen is extremely volatile, a lot more so than gasoline." True... and has a lower energy density. Still experiments with automobiles show that when a car is wrecked, and the H2 tank breached, the gas --- being so very light --- rises so fast that fire is much less dangerous than a gasoline fire. "It also takes a lot of energy to produce from say water. Eloctrolysis to disassociate the hydrogen from oxygen is expensive." Also true. Fortunately there are some very promising technologies under development that possibly will greatly lower the cost of producing H2 from water. For example, there is a photocell under development that uses sunlight as the energy input (photons, not electrons, being the input energy) to hydrolize water and produce Hydrogen and Oxygen gases....
